Designed to mitigate tidal flooding and sea level rise, the pump station has the capacity to move approximately 80,000 gallons per minute and serves a drainage area of roughly 84 acres. The project included construction of a 96-inch trunk line to collect flows from Collins Avenue and surrounding streets, as well as a new treatment structure equipped with axial pumps and overflow controls for system redundancy. The design also incorporated trash racks, flow splitting weirs, and resiliency features to prevent tidal intrusion. In addition, the project included construction of approximately 200 feet of higher seawall with a minimum top elevation of 5.70 feet NAVD, ensuring long-term flood protection and serving as a prototype for future stormwater pump stations throughout the City.
